INSTRUCTIONS TO ABSTRACTORS, giving the NOMENCLATURE AND SYSTEM OF NOTATION ADOPTED IN THE ABSTRACTS. 1. Before beginning to write an abstract, it is desirable to read tlirough the whole of the original paper, in order to form a judgment as to its importance, and as to the scale on which the abstract should accordingly be made. 2. The abstract should mainly consist of the expression, in the abstractor's own words, of the substance of the paper. 3. The abstract should be made as concise as possible, consistently with a clear and accurate statement of the author's results or theories, due regard being paid to their import. 4. If an abstract of a paper on the same subject, either by the author of the paper abstracted, or by some other author, has already appeared, note should as a rule be made of this fact. Important references to the researches of others quoted by an author should be reproduced in the abstract. Always employ figures instead of Roman numerals for references, thus :— Annalen, 221, 92, instead of ccxxi, 92. 5. If an abstractor is acquainted with papers previously published by other authors containing statements either practically identical with, or opposed to, those in the paper abstracted, and to which no reference is made, he should notice their agreement or contradiction in a foot-note. 6. As a rule, details of methods of preparation or analysis, or, generally speaking, of work, may be omitted, unless such details are essential to the understanding of the results, or have some independent value. Nomenclature. 7. Employ names such as sodium chloride, potassium sulphate, ethyl acetate, and use the terminals ous and ic only in distinguishing compounds of different orders derived from the same elementary radicle; such, for instance, as mercurous and mercuric chloride, sulphurous and sulphuric acid. 8. Term compounds of metallic and alcoholic radicles with the group I , l i r ' ¦i .•
